Maintainance Tips
• Care of Projectors
1. Do not place projector in too warm or too cold room, because the high temperature or
low temperature will shorten lifespan of the device. The working environment would be
5°C-35°C better.
2. If there are black spots on the projection screen, please don't worry. Please contact
via email, we can send you a video about how to remove the dust.

3. The projector shall be strictly protected from strong impact, extrusion and vibration.
4. Lens, as the core component of the projector, is directly related to the picture
definition and effect. Clean the lens whenever you noticed dirt or dust on the surface.
Use a canister of compressed air to remove dust from the lens. If there is dirt or
smears, use the cleaning cloth to gently wipe the lens surface.
